Application filed. January 31, 1510. -Serial No. 5e1,063.-

To all whom 'it 'mcy concern;

Be it lmown that I,V DINIs Denny, a citizenofthe United States, residing at Parkersbnr in the county of Wood and Sta'Qfm; tain new" 'anduseful Improvements in Rein- `forced,J 4Concrete Structures; and I do `de- Clare "the ffollowingto be a full, clear, and

exact description ofthe invention, such as will enableothers fskilled inthe art to which itappertainsmakeand use the same.

This ni ntion l,relates to improvements in reinforced. rete Wall construction.

,Y ,Thcobjecgofthe invention is to provide` `a"jvvallr ofl thischaracter having means to permitthe eiqiaiisini'ofv the wall without rupture and torfill the spaces-due to the contraction of the Wall so that no cirevioes will beleftfor moisture to collect.` 1n and cor- .rode the'metal reinforcement.

inforcing bars.

Referri g more particularly. to the drawings, 1 denotes the wall in the opposite sides of which are set reinforcing bars 2, which may be of T, angle-iron or any other suitable construction, said bars being here shown as angle-iron bars, one side or edge of which projects transversely into the wall as shown. The inner projecting edges or sides of the bars are securely tied together by braces 3 or other .suitable fastenings and when the wall is' bein formed boards are laid against the outer si es of lthe bars to form the mold for receiving the concrete.

The bars @are arranged at suitable intervals along thelength of the wall and with the inwardly extending sides of the bois is engaged a cushioning strip 4 formed of suitest Yirginia, have invented cerable elastic or resilient material which, when the wall expands, will be compressed, thus preventing the bulging or rupture of'the 'sull from such expansion. When the Wall 4again contracts, Y,the cushioning strip 4 will expand and thus fill up the space which of the Wall and in which would `collect moisture. The collection of moisture in such spaces or crevices left by the contraetin of ing bars and thus weaken the wall.

.. From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

' Various changes in `the form, proportion and the minor details of construction may 7he resorted to without departing from' the l,fllinciple or sacrificing any of the advanwould otherwisel be left by'such contraction the'wall would in time corrode the rein orcges of the invention, as defined in the appended claim. .y

` Having thus described my invention what I claim is: l

In a concrete wall construction, the combination of two wali sections, o vertically disposed reinforcing structure arranged transversely between said wall section and consisting of angle metal uprights united by crossed braces and having inner lianges extendin between the opposing wall sections and side faces of one of the Wall sections, and an upright rectangular sheet of elastic cush- Iioning material arranged in said supporting tions, said cushioning sheet extending from bottom to top of thewall and arranged en A nuns WHQLIAM DALEY.
